Magnetic Nanoparticles Adapted for Specific Biomedical Applications

Magnetic nanoparticles are used in different biomedical applications, whereby each application requires specific particle properties. To fulfil these requirements, particle properties have to be optimized...

Seamless stitching of tile scan microscope images

For diagnostic purposes, optical imaging techniques need to obtain high-resolution images of extended biological specimens in reasonable time. The field of view of an objective lens, however, is often...

Surface corrugating direct laser writing of microstructures in ternary chalcogenide films using a continuous-wave super-bandgap laser

Direct laser writing using a tightly focused 442 nm continuous-wave laser was applied to corrugate the surface of ternary As-S-Se chalcogenide thin films with high spatial resolution. The topography of...

Mode Coupling in Few-Mode Fibers Induced by Mechanical Stress

We investigate mode coupling in few-mode fibers induced by homogeneously and periodically applied mechanical stress. To view the power transfer between individual modes a modal decomposition is performed...

Optical glass fiber tips for photonic micro-sensor systems

The application potential of sub-structured fiber tips in optical sensor technology and photonic microsystems is high. The miniaturization of sensor systems and the technical implementation using optical...

Influence of surface pre-treatment on the electronic levels in silicon MaWCE nanowires

Deep Level Transient Spectroscopy (DLTS) was performed on n-doped silicon nanowires grown by Metal-assisted Wet Chemical Etching (MaWCE) with gold as the catalyst in order to investigate the energetic...

Dielectrophoretic positioning of single nanoparticles on atomic force microscope tips for tip-enhanced Raman spectroscopy

Tip- enhanced Raman spectroscopy ( TERS), a combination of Raman spectroscopy and scanning probe microscopy , is a powerful technique to detect the vibrational fingerprint of molecules at the nanometer...

Pinus sylvestris switches respiration substrates under shading but not during drought

Reduced carbon (C) assimilation during prolonged drought forces trees to rely on stored C to maintain vital processes like respiration. It has been shown, however, that the use of carbohydrates, a major...

Online investigation of respiratory quotients in Pinus sylvestris and Picea abies during drought and shading by means of cavity-enhanced Raman multi-gas spectrometry

Photosynthesis and respiration are major components of the plant carbon balance. During stress, like drought, carbohydrate supply from photosynthesis is reduced and the Krebs cycle respiration must be...
